Abnormalities of the reproductive tract that consist mainly of obstructions that partially or totally block the flow of sperm and/or seminal fluid. Some of these abnormalities may be present at birth (congenital), others may have occurred after infection of the urogenital tract, whereas others may have resulted from previous surgery.
This occurs when the production of the sperm is inhibited.
These disturbances prevent sperm from reaching the female.
These disorders prevent sperm from meeting and successfully penetrating the egg in the female genital tract.
